I need a Digital SLR. I currently don't own any lenses of any brand. I will be shooting horses in motion and landscape/nature (tropical beaches). Would you recommend me the D90 or the 50D? The reason I won't go any higher than the D90 with Nikon is because I like the auto mode and presets that the D90 has. The D300 is too much of a pro camera. So which one? D90 or 50D? p.s. I don't care about the movie function on the D90. I already own a Canon HF10.
